Tammy just sent me this magical math trick-

1) Punch the first three digits of your home phone number into your calculator (without the area code.)

2) Multiply by 80

3) Add 1

4) Multiply by 250

5) Add the last four digits of your home phone number

6) Add the last four digits of your home phone number again

7) Subtract 250

8) Divide by 2

Recognize the number?
